  "img_finding": "Image findings: ventricular volume measures 27,943 mm³, 27.5% below the reference mean. With a Z-score of -0.66 (25.5th percentile), this represents normal volume ; hippocampal volume measures 6,871 mm³, 9.1% below the reference mean. With a Z-score of -0.89 (18.7th percentile), this represents normal volume ; whole brain volume measures 1,105,100 mm³, 2.4% above the reference mean. With a Z-score of 0.31 (62.1th percentile), this represents normal volume ; entorhinal cortex volume measures 4,196 mm³, 2.3% above the reference mean. With a Z-score of 0.16 (56.3th percentile), this represents normal volume ; fusiform gyrus volume measures 19,004 mm³, 0.9% above the reference mean. With a Z-score of 0.07 (53.0th percentile), this represents normal volume ; middle temporal gyrus volume measures 22,057 mm³, 3.4% above the reference mean.

  "gpt_diagnosis": "Reasoning: All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, middle temporal gyrus) are within normal ranges, with no significant atrophy. Cognitive scores (MMSE 28, MoCA 24) are also within normal limits for age, and amyloid PET (AV45) is normal. APOE4-negative status further reduces Alzheimer's risk.  \nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
